characteristics that indicate a bulb is approaching the end of its lifespan.
Initial symptoms of end-of-life are characterized by low light output and/
or intermittent starting. Visual signs include blackening at the ends of
the arc tube and electrode tip deterioration. Note that HID bulbs contain
metals, including mercury, that are harmful to the environment. Please be
responsible in arranging for proper disposal of an HID bulb.
The bulb and ballast are sensitive to external operating temperature.
Although HID light technology doesn't generate heat equal to that of a
halogen light, it should be treated like any other dive light. The HID lamp
should only be operated while in the water, to provide proper cooling for the
lamp assembly. While transporting your HID light, please don't leave the light
in direct sunlight or in a car's interior on a hot day.
21 watt HID Light Head
Halcyon's workhorse light, the 21 watt HID, allows full adjustability and easy
bulb changes in a conventional test tube style design. Light output is similar
to a 100 watt halogen light at a fraction of the power consumption. Halcyon
21 watt HID lights include our exclusive ultra-bright reflector. We’ve designed
the parabola of the reflector specifically for diving applications, where a
sharp spot is beneficial for signaling. The surface is spun and polished to
our specifications and will not chip or flake like metal film vacuum-coated
reflectors. Combined with the extended protective cowling on our light head,
the Explorer lights throw out an intensely focused beam of bright, white light
that you can rely on in the most challenging of situations.
21 watt HID Light Head Operation
The one-piece machined Delrin slug is temperature resistant and completely
non-corrosive. The slug assembly consists of a bulb socket, bulb, test tube
and cord. The bulb slug contains three O-rings. The two O-rings closest to the
bulb actually provide the water-tight seal while the base ring cushions the
glass tube.
The focus of your light may be set by loosening the locking screw on
the Goodman Light head and moving the bulb slug assembly backward
or forward in the light head. To avoid the potential of breaking the bulb
covering, be careful not to tighten the screw down on the glass tube. The
focus should be set so that the beam forms a tight circle several feet in front
of you, allowing for brightest illumination and more convenient signaling to
one's dive buddy.
Never leave your light on while at the surface! Without the dissipating effect
of the water, the heat generated by the bulb can accumulate in the light
head, damaging the assembly's components.
Should the bulb assembly become difficult to focus, make certain that
the nylon adjustment screw is loose and not binding the assembly's
